feat(footer): add heise online press coverage link

[raifdmueller]

What

Adds the heise online article about Semantic Anchors to the footer:
https://www.heise.de/news/Semantische-Anker-verkuerzen-den-Kontext-fuer-das-agentische-Coden-11311061.html

It goes in a separate row — "Featured in" (EN) / "Bekannt aus" (DE) — distinct from the existing "As seen on" / "Zu Gast bei" row.

Why a separate row

"Zu Gast bei" (guest appearance) fits the podcast/live-coding entries (HMZE, rabauer.dev) but not a news article — you weren't a guest at heise, they reported on the project. Mixing it in would read wrong in German. A dedicated press row keeps the semantics clean in both languages.

Logo handling

• Uses the official heise online mark (navy circle + white "h.").
• Placed on a small white chip so it stays legible in both light and dark mode (the navy circle would otherwise blend into the dark footer).
• The bundled SVG has the prefers-color-scheme media query stripped, so it renders predictably against the site's class-based dark mode rather than following the OS theme.

Verification

Built and visually checked the footer in light and dark mode; confirmed the heise SVG loads, the new row renders, and DE shows "Bekannt aus" / EN "Featured in". Lint + Prettier clean.
